Question

What is the pH of a solution containing a hydrogen ion concentration of 1.0 x 10^-3 M?

A. 3

B. 5

C. 7

D. 9

Answer 1

The pH of a solution containing a hydrogen ion concentration of 1.0 x 10^-3 M is 3.

Step-by-step explanation:

The pH of a solution can be calculated by taking the negative logarithm base 10 of the hydrogen ion concentration. In this case, a hydrogen ion concentration of 1.0 x 10^-3 M corresponds to a pH of 3. Therefore, the answer is A. 3.
